| This study is a model on the Migration Characteristics which developed by using the equations for conservation of mass, momentum and for lateral stability of the streambed, an the model can be examined for magnitude and location of near-bank bed scour as well as rates and direction of meander migration in which sine-Wave type rivers(SWR) of the small sinuosity. It is evident from this study that the transverse bed slope factor B' and transverse mass flux factor $ play significient roles, and show reasonable that the values are B'=4.0 and $=0.4 respectively . It will be a useful guide in planning, design, construction, and development of SWR river-basin projects |
